Twitter hacking shows social media's security problems

The hacking of the Associated Press's Twitter account yesterday has raised concerns over the trustworthiness of information spread through the site, Bloomberg reports. Stocks fell 1 percent Tuesday after a fake tweet about explosions at the White House appeared on the AP's account. The incident puts pressure on the tech company to improve security for users, Wade Williamson, a senior security analyst at Palo Alto Networks Inc., a provider of network-protection tools, told Bloomberg. "The account that got compromised is the big difference here, as opposed to the traditional impersonating-a-celebrity to say something shocking," Williamson said. AP has suspended its Twitter account and the Federal Bureau of Investigation is investigating the matter.
